Laser biostimulation or cold laser therapy involves the use of low powered lasers to stimulate cellular function and hair growth.

Low Level Laser Therapy or LLLT (also known as photobiomodulation, cold laser therapy and laser biostimulation) is a medical treatment which uses low powered lasers to stimulate cellular function. Low Level Laser Therapy is a safe form of light treatment that has been in use for more than 40 years to treat many conditions including the genetic forms of hair loss, male patterned baldness and androgenetic alopecia. Low Level Laser Therapy is suitable for both men and women with thinning hair or patterned baldness. More specifically, LLLT involves the application of monochromatic, coherent photonic energy to biological tissues with the objective of inducing a therapeutic reaction. The therapeutic reaction may be controlled with variables of dosage, frequency and wavelength, to produce specific, reproducible results on target cells.

History of low level laser therapy

In 1923 Russian researcher Alexander Gurwitsch made a critical discovery in the evolution of modern low level laser therapy when he discovered that cells emit infrared light as a means of intercellular communication. He also found that this light could be transmitted from cell to cell without any physical contact, even when the cells were housed in adjacent test tubes. Gurwitsch named the phenomenon of infrared emission, “mitogenetic radiation”.

Modern low level laser therapy was however born out of the research of Endre Mester of Semmelweis University Budapest. In 1966-67 Mester conducted a series of experiments demonstrating that low intensity red and infrared laser light, accelerated wound healing and hair growth, enhanced the formation of blood vessels, increased collagen synthesis and promoted enzyme synthesis. In 1974 Mester founded the Laser Research Centre at Semmelweis and today is credited as the discoverer of the positive biological effects of low powered lasers, or low level laser therapy as it is now known.

Laser therapy has subsequently been studied and used in clinical practice for more than 40 years and there are literally thousands of studies and published articles attesting to the efficacy of LLLT.
